IMPROVEMENT IN LEATHER-PUNCHING MACHINES:

The Schedule referred to in these Letters Patent and making part of thesame.

I, JoHnMATHEIs, of Ottawa, in the county of Lal Salle and State ofIllinois, have invented a certain Improvementin Leather-PunchingMachines, of which the following is a specification.

My invention Jrelates to Amachines for punching leather straps forlynets, vand for which-I have al ready obtained two patents, one datedJuly 21,1868, and one dated May 18, 1869, and consists in an alter@ation of the same machines, but especially thelatter, whereby it becomesadapted to a new purpose, which is to pierce the holes necessary to sewtogether the several thicknesses of leather straps orbelts which make atrace for a harness, as also for any other kind of work in which two ormore straps of leather' are united by 011e or more longitudinal seams.

'The object of my invention is to pierce said holes much faster and moreregular than can be done with an awl and by hand labor, as has been doneheretofore7 while, at the same time, the work can be intrnsted to-a lessexperienced workman or even to au appren' tice.

Figures l and 2 are side ele\i'ati,ons oi' that part of the machinewhich embodies my present improvement;

Figure a plan and Figure 4 is a. vertical section through ab, fig. l. Imake a hinged joint inthe punching-bar D ofthe rpatentN,0.90281, inabout the middle of its length,

and removing the lower part I replace it by the punching orpiercing-bar, shown in the drawing. This consists of a vertical bar, A,to the bottom of which is attached a cross-head', B, which holds theneedles or awls (l C.

The cross-head Bis made 'hollow in t-wo or more divisions, eachdivision, containing a small notched metal block,'E, which is pressedagainst the needle by means of the scrwsF F.

The notches G Gl G in the block\E are for the purposeof allowing theneedles G Gto be set more or less apart, so 'as to accommodate strapsof.` different widths.

The machine is used in the same manner asfor punching holes, only theneedles or awls merely pierce through the leather without taking off aburr. After the whole strap is thus pierced at regular intervals theworkman inserts the thread with a'comrnon needle and liuishes the seamin the ordinary manuel'.

A punching-bar, composed ofthe vertical bar A,

the cross-head B, the blocksE E with uothes GG G, the screws F F, andthe needles or awls C C, in connection with a machine forpunchiugleather straps for 1ly'nets, substantially as aud for thepurpose described.
